    • The present invention provides a method of preparing a toner includes: adding a first external additive having an average primary particle diameter of between about 30 nm and 200 nm to toner particles including a binder resin and a colorant and stirring the first external additive with the toner particles to form a first external additive layer on the surfaces of the toner particles; and adding a second external additive having an average primary particle diameter between about 5 nm and 30 nm to the toner particles having the first external additive layer and stirring the second external additive with the toner particles to form second external additive layers on the first external additive layers. A stirring line speed of the first external additive is less than a stirring line speed of the second external additive. The method of preparing a toner increases the endurance of the toner and prevents a developing member from being contaminated. External additives having different average primary particle diameters are sequentially added to toner particles including a binder resin and a colorant so that external additives having greater average primary particle diameters are uniformly coated on the surface of the toner particles. Accordingly, a uniform charge and the fluidity of the toner are improved and contamination of a charge roller and other developing members due to a separation of the external additives is prevented.
    • 本发明提供制备调色剂的方法,包括:将平均一次粒径为约30nm至200nm的第一外部添加剂加入到包含粘合剂树脂和着色剂的调色剂颗粒中,并将第一外部添加剂与调色剂 在调色剂颗粒的表面上形成第一外部添加剂层; 和将具有约5nm至30nm的平均初级粒径的第二外部添加剂加入到具有第一外部添加剂层的调色剂颗粒中,并且用调色剂颗粒搅拌第二外部添加剂以在第一外部添加剂上形成第二外部添加剂层 层。 第一外部添加剂的搅拌线速度小于第二外部添加剂的搅拌线速度。 制备调色剂的方法增加了调色剂的耐久性并且防止显影构件被污染。 将具有不同平均初级粒径的外部添加剂顺序添加到包含粘合剂树脂和着色剂的调色剂颗粒中,使得具有较大平均初级粒径的外部添加剂均匀地涂覆在调色剂颗粒的表面上。 因此,调色剂的均匀充电和流动性得到改善,并防止了由于外部添加剂的分离导致的充电辊和其他显影元件的污染。

    • A toner having toner particles containing a binder resin and a colorant; and a first external additive having 0.1 to 3.0 wt% of large silica particles with an average particle size of 20 to 200 nm; a second external additive having 0.1 to 3.0 wt% of small silica particles with an average particle size of 5 to 20 nm; a third external additive having 0.1 to 2.0 wt% of hydrophobic titanium dioxide microparticles with a resistance of 10 5 to 10 12 Ω.; and a fourth external additive having at least one of 0.1 to 2.0 wt% of conductive titanium dioxide particles with a resistance of 1 to 10 5 Ω. and 0.1 to 2.0 wt% of positively chargeable aluminium oxide particles. Therefore, a thin toner layer with a uniform toner amount is formed on a toner carrier and stable charge distribution and toner flowability are maintained for a long time, thereby resulting in prevention of fog and toner scattering, and improvements in developing efficiency and toner durability.
